Lee,
I have been trying to keep to myself lately unless I see some new guy getting sucked down the drain with the dishwater. Basically the primer is the problem. Primers are real old technology and as Remington figured out a long time ago,you gotta smack the hell out of them to make them consistent. The Rems and Pandas use 24 lb springs and massive firing pins,smasha,smasha,smasha ! Bat's and Farleys use lighter 18lb springs and dainter firing pins for the sake of smooth operation, but if these springs get weak( and they all do) ignition and accuracy are compromised. The general rule with any BR action is to change FP springs regularly.If your shooting a Bat or Farley and even a new spring dosn't fix suspicious ignition problems then a visit with an accuracy enhancing gunsmith( like Dave Bruno or Wayne Campbell) is in order.Ignition is everything in Benchrest and can't be ignored.A new expensive action does not come with a perfect ignition gaurantee.There are many bolt related reasons for poor ignition( it's not just the springs), so if you think you have a problem,get it to someone who can fix it.On the other hand, If your gun is shooting lights out,leave it alone and go win some wood.
